MOPAR part numbers for wiper arm and crank

[MR291]

I am installing a three speed wiper setup in my 70 Cuda.  I bought the pieces but I am having difficulty with the crank and the bushing in the linkage arm.  Stud on crank is not long enough or bushing is incorrect.

There seems to be a lot of different numbers out there for what will work in the car.  There used to be site "lighteningjar" that had a great search engine for confirming parts / interchangeability but that is no longer working.  Is there anywhere else that I can match the numbers on my pieces to confirm whether they are correct or not.

The linkage arm is 3431 514 58622 and the crank is 2822 28 58622.

Thanks.

I have a wiper arm # 3431 514 58622 and was told by Kim that it is a 2 speed arm.

I looked this up in my 70/71 Parts Catalogue and your "3431 514" doesn't show up. It's probably from later years. I also did this conversion on my car and the correct part numbers for the var/3speed are:
2822 293 - link that goes from motor's crank to left pivot
2822 289 - crank coming off the motor
